No, tomcatB is using tomcat6. > Can you make that also tomcat8 but keep java8? > > > I mean A is java8 and tomcat8.. so make a C that is tomcat6 and java8 > > I don't think so. This is a requirement of the software company whose application solution we use. They are requiring us to move to tomcat 8 with jdk 1.8. If we try to mix tomcat8 with jdk 1.6, supposedly we would have problems. I guess all this is being driven by the need to switch to TLS 1.2. I'm not sure if that would be a function of tomcat or java. --Eric
